' Application filed November 19, 1927. Serial No. 234,305.

My present invention relates to an im* proved brush which while adaptedfor various purposes, is particularly designed for cleansing theinterior of tubes of milking machines. As is well known, the milkingtubes are of a general funnel shape, that is, they comprise at least twoparts of ditering diameters. rlhe device of my invention is designed forthe purpose of cleansing tubes of this character and is thereforefashioned and shaped to adapt it for this type of tubes. Under existingconditions, two brushes are required for cleansing the tubes, but by theuse of the brush of my invention, a single brush performs the functionsof the two brushes.

The invention consists in certain novel combinations and arrangements ofparts between the brush and the brush handle whereby these parts may beseparated in order that the brush may be cleansed, or for the purpose ofsubstituting or interchanging one brush for another when required.

The invention consists in certain novel combinations and arrangements ofparts as will hereinafter be more fully set forth'and claimed. q

In the accompanying. drawings, I have illustrated one complete exampleof the physical embodiment of my invention wherein the parts arecombined and arranged 'according to the best mode I have so far devisedfor; the practical application of thev principles or my invention. 1

Figure l is a view in side elevation of a brush embodying my invention;

Fig. 2 is a similar view but showing the brush inserted within a milkingtube;

Fig. 3 is an enlarged detail sectional view showing theV ljoint betweenthe detachable handle and the brush;

Fig. lis a. sectional view at line 4 4 of Fig. l;

Fig. 5 a sectional view at line 55 of Fig. 3; and

Fig. 6 is a sectionalview at line 6-6 of Fig. 3.

In carrying out my invention, the brush is fashioned with a main largerounded member l which at 2 tapers down to the reduced or pointedvmember 3, and this specially formed brush is designed to be inserted androtated within the tube of the milking machine shown in Fig. 2 which hasalarge cylindrical part 4, a conical portion 5 and a reduced cylindricalportion 6. The corresponding parts of the brush of course lit into thesetubular members, and the brush may be to the twisted stem -7 thatextends throughout n the length in the interior of the brush, and thetwo shanks 8 and 9 at the end of this twisted stem are provided withangular heads l() that project at right angles from the shanks 8 and ,9.rllhe twisted stem is made up of wire and theshanks 8 and 9 possess aresiliency and are of sufcient length to permit them being squeezedtogether or extended as indicated in Fig. 3 and dueto this resiliency oftheseshanks the brush is detachably secured to the ferrule 1l of thehandle of the brush. This ferrule preferably is flattened as -indicatedin Figs. 5 and 6 and is provided with side slots l2 inits walls toaccommodate the heads l0 of the shanksr and 9. It will be apparent thatthe Shanks 8 squeezed together vand inserted in the open end of theferrule and then when the shanks are released the heads,`due toresiliency of the Shanks, ,are projected through the slots l2 to lockthe handle vto the brush. To guide the heads into their slots, l providea spreader 13 which comprises a metal plate of somewhat U shape which islocated transversely of the ferrule and has its ends fixed in oppositeslots lt in the wall of theferrule. This spreader 13 forms an abutmentagainst which rthe Shanks 8 are pushed and theroundeu end of thespreader causes the heads l0 to slip into the slots l2 to lock theshanks.

The handle 15 is vin the form of a loop made out of wire similar tothestemr of the brush, and the ends 16 of this loop are welded orotherwise secured at 17 in the smaller end and 9.1nay beof tho taperingferrule ll, as shown in Fig. 3.

rlhe spreader 13 is a Vresilient member and 1s designed to perform thefunctions of a spring that holds the two heads l0 vof the shanks 8 and 9in their slots or sockets l2, and this resilient spreader 13 bypreventing inward movement ofthe free ends of the shanks 8 and9 locksthese heads in their sockets to prevent displacement of the handle fromvthe brush, or of the brush from the handle.

Having thus fully described my invention,v

what I claim as new and desire to secure by Letters Patent is Thecombination with a brush having a 5' twisted wire stem, resilient Shankson said stem, and laterally projecting heads at the ends ofv saidShanks, of a separable handle posed sockets in its wall to receive saidheads, y and a transversely extending U-shaped resil- 10 ent spreaderlocated in the path of said heads having its ends anchored in the`ferrule and adapted to project said heads through the walls of theerrule. y

' In testimony whereof I affix my signature.
